FLUSHING MECHANISM. 2

Application filed September 1, 1920. Serial No. 407,375.

To all whom it may concern:

Be it known that I, FLETCHER Rooo, a citizen of the United States, residing m the city otlValla Walla, county ofWalla Walla,

and State of Washington, have invented certain new and useful Improvements in Flushing Mechanisms, of which the follow inq isa specification.

lly invention relates to flushing mecha' nisms of the general character shown and described 1n my co-pending application,

Serial No. 337,222, and has for its principal object to simplify and make more practical a flushing mechanism of the character referred to. In my application above referred to, the mechanism is connected with and operated by the'seat or the cover of toilet; In this application, the mechanism is set into action by simplypressing a lever. The mechanism will be clearly understood from the following description of one practical embodiment of my invention, taken in connection with the accompanying sheet of" drawings, in 'which,-

Figure 1 is a vertical sectional view through my improved flushing mechanism; Figure 2 is a horizontal sectional view, taken on line 1-2 of Fig. 1;

Figure 3 is a horizontal sectional view taken on line 34: of Fig. 1, and

Figure 4 is a view of a detail.

Referring now in detail to the drawings, my invention ashereembodied, comprises an outer cylindrical casing, 1, connected at its-lower end with a suitable supply of water, under ressure, by means ofa pipe, 2, and at its upper end, connected'by means of the pipe 3, with a tollet, or other recep tacle to be intermittently flushed or; sup-'- plied with a quantity of water. An'1nner, smaller cylinder, 4, is suspended'm the upper end of the main casing 1, as shown,-w1th suitable upper end and the cap, 6, of the outer casmg.

vided in its side with a series of hole's,-f7.

Adjust-ably mounted through the lower end of the inner cylinder 4:,- is a slotted screw 8,

through which passes a-rod, 9, provided at in the outer casing, 1, as'indi'cated; and the Said inner cylinder ise1osed' at its lower end,- and neanits'upper end is prois finished. I

A hearing roller, 1 18, is also mounted on. the cross bar 145, and bearsagainst the back of the rack, asshowmwi 5 Near the lower end of the outer casing,.1,, h is an annular fiangeor. floor, 1 9, t0;the= u'na derside of which is attached a spider-like member, 20, having-the fibor=,21.*and "the short cylinder portion, 22. A valve disc, 23, covers the underside of the. opening through the floor, or flange l9, and is1attaohed tothe lower end'i'of the rac'lr 1 1,-as indicated Ihe lower stem portion ofsaid=valve, 23,

The use and operationof' my. invention, as shown for illustrative nrp sea may be briefly described asfollowsz-Thesupply of water from the' pipe 2, is shutout byth-e closed valve member"23', in theposition shown. In order" to set the device in "ope'r'ation for flushing, the lever 17 is depre'ssed by hand. This turns the gear 12','-n'1*ov'es' therack 11 and-rod" 9, andvalve'23'idowng-thus allowing water to pass upwardly through the annular flange ormember 1-9, up arojumr the inner cylinder 4, through the" hole's 7',

"and out through the pipe atthe up er nd gasket 5, interposed between its" to the toilet or receptacle tobe flushed. Wateralso passes through the 'slotted screw 8, and lifts-the loose piston 25, onthe'rod 100' 9 until it engages with the screw sleeve lQti at its upper end, which'Topera tes i to raise the rod, 9,the -rack 11, and the -valve' 23 to closed position, as shown and the action I 4 I I, I- When the loose piston 25 has' beencarried j above the holes -7 in the upper endof the outer casing 1, the full force ofthe water then acts on the loose pis'ton 25 andis'su'f ficient -to lift the rod-, 9-,' rack, 11and the 1-10 valve 23 into closed position, as shown in the drawing.

In order to prevent the valve .28 from closing too suddenly and thus causing a knock or other objection, the piston-like member 24 is provided, which moves in the short cylinder, 22, and operates to control the movement of the valve, rack and rod upwardly, as will be understood from the showing in Fig. l of the drawing.

I havenot shown my flushing'mechanism in connection with a stool or other basin, but it' is to be understood that it is connected at its upper end, by means of the pipe 3 with the inlet to the stool or basin, and is intended to be practically noiseless on account'of avoiding the gravity feed of water into the basin to be flushed.

I am aware that changes in the details can be made in my invention as here illustrated, without departing from the spirit thereof, and I do not, therefore, limit my invention to the showing made, except as I may be limited by the hereto appended claims.
